TFS248E.doc version 6.0 08.04.2002 VI TELEFILTER Measurement condition Ambient temperature: Input power level: Terminating impedances at fc *) 23 0 Input: Output: Filter specification TFS 248 E 1/5 Characteristics Remark: C dBm 560 || -5.9pF 500 || -6.3 pF The reference level for the relative attenuation arel of TFS 248E is the minimum of the pass band attenuation amin. This value is defined as the insertion loss ae. The nominal frequency fN is fixed at 248,6 MHz without any tolerance. The given values for the relative attenuation arel and the group delay ripple have to be reached at the frequencies given below, even if the centre frequency fc is shifted due to the temperature coefficient of frequency TCf in the operating temperature range and due to a production tolerance for the centre frequency fc.
